In the conditions of the Republic of Belarus there were the basic biological norms of a process of integrated composting of agroindustrial complex wastes by polyculture of terrain and soil organisms, the biomass of which is considered to be valuable raw materials of animal origin. The productivity of is 39.5 kg/ square meter. Receiving protein raw materials of animal origin was investigated in the course of integrated composing of agricultural complex wastes and their use as starting feed for fish. Starting feed prepared on the basis of raw materials satisfies feed needs of young fish – Poecilia reticulate and enables to achieve similar results in comparison with specialized feed provided that young fish is bred under optimal temperature conditions. There were four variants of the tests of correction of protein feed materials protection based on the production of heli- and vermiculture. There were analyzed of results of growing of guppy (Poecilia reticulata) fingerlings with use of special and experimental start feeds. Research results showed that content of composting substrate and components of mollusc feed influenced the productivity of some components of the system at combined growing of vermi- and heliculture. There were no changes in the system of productivity and feed coefficient. Application of wheat powder and shorts as the main nutritive components increased the system productivity of molluscs in comparison with barley powder and shorts. Content of mollusc feed influenced the final balance of components in the system production. Substrate content influenced the productivity and the part of the total production of the Lumbricus rubellus system. It was shown on the total biochemical indexes of the obtained raw materials.
